"textContent": "A lithium-sulfur secondary battery including a positive electrode, a negative electrode, a separator, and an electrolyte. The electrolyte contains a cyclic carbonate, and the cyclic carbonate is fluoroethylene carbonate, vinylene carbonate, or a combination thereof. The amount of cyclic carbonate in the electrolyte is more than 0 ppm and less than 1,000 ppm based on the total weight of the electrolyte. The cycle performance of the lithium-sulfur secondary battery can be improved because the lithium-sulfur secondary battery contains a cyclic carbonate in the electrolyte.",
